SWITCH STAN D.

SPECIFICATION forming part of Letters Patent No. 398,354, dated February 19, 1889.

Application filed November 26, 1888. serial No. 291,875. (No model. 7

To all Z/J/7L07H/ it may concern:

Be it known that I, AXEL A. STROM, a citizen of the United States, residing at Austin,

in the county of Cook and State of Illinois, 1 have invented a new and usefulImprovement in Switch-Stands, of which the following is a releasin the operatingdever from a peripheral recess in the revoluble table, be readily r3- tated, but wherein, when the operating-lever is in its normal hanging position in a peripheral slot of the table, the spindle, table, and a clutch are interlocked and so held by the yielding force of a stilt distended spring, requiring a force like that from the flange ot a passing locomotive acting against the movable rail of a split switch to turn the spindle, and with it the iable, thereby turning the movable part of the clutch on the immovable part against the resistance of the spring.

The object of my invention is n'lateriallyto simpli ly the construction and operation of the species of swiieh-staml referred to, thereby considerably reducing the cost of manufacture, and at the same time to afford a generally-improved construction of the device.

0 In the accompanying drawings, Figure 1 is a vertical partly-broken section of a switchstand of my improved construction. Fig. 2 is a plan view of the revoluble table, showing the relative positions of the radial peripheral 3 5 slots. Fig. 3 is a broken sectional viewot the upper part of the device, the section being taken at an angle on a horizontal plane to that shown in Fig. 'I. Fig. a shows the two parts of the clutch in engagement; and Fig.

40 5 represents thecrank of the vertical. spindle shown in section, and which is normally off a dead-center with relation to the line of the switchconnecting bar. (Not shown.)

A the hollow standard, inside oi which,

4 5 preferablynear its lower end, is a web, r,sup-

porting an tinternally-rectangular socket, q.

B is the table, having a central opening, around which is a sleeve,B, which enters the standard A when the table adjusted in its position of resting on the upper end of the hollow standard, as shown, and the table,

l which is circular, contains radial peripheral slots p.

(Shown to be four in number and ninety degrees apart.)

' Cis a elutclnformed in two parts, each having a number of similar teeth, the lower part,

a, being preferably annular and having a narrower rectangular hollow shank, n, to

fit in the rectangular socket q, whereby it is rendered stationary, and the upper part, m, having a rectangular shank, m, of the same diameter through diagonally-opposite corners as the part m, which, like the part 71, may be annular, the shank m fitting into the lower end of the sleeve which should be rectangular internally to receive it. \Yhen the teeth of the part on mesh, as they ordinarily do, with those of the part 11, the shank 71/ extends for some distance out of the sleeve.

I) is the spindle, provided on its lower end with a crank, II), the spindle .extemling through the opening in the clutch and out at its upper end through the top of the standard, where it carries a signal, E,and the crank is normally off a dead-center. 75

F is a yoke surrounding the spindle, to which it is keyed, and having a flange, Z, at which it rests on the table 1:), the yoke being hollow, and, by preference substantially so, above and below the flange, the lower part extending some distance into the circular opening in the table, which it fits, and thereby affording bearing for the yoke inside the table as well as upon the upper surface thereof. 8 5

One side of the yoke, above the part which enters the table, is provided with a housing, F, closed at its top, thereby forming a firm connection with the main body of the yoke and rendering the latter strong throughout, 0 and having an opening, 1', in its flaring base to admit the operating-lever I, which is pivotally connected with the housing, as shown. The side of the housing is also provided with an opening, I, to admit through it the staple 5 or eye 1. on. the operating-lever, with which the ordinary padlock (not shown) on the end of a chain, engages to lock the lever against rmnoval from a recess in the table.

G; i a stiff spiral spring resting on the shank on. of the upper part of the clutch. and surrounding the spindle inside the sleeve B,

the springbeing confined between the clutch and the yoke F through the medium of a short sleeve, H, forming a continuation of the yoke, and which may or may not be integral therewith.

The operating-lever I normally hangs at an angle at which it may enter a recess, 1), in the table B; To turn the spindle for setting a switch by hand, the lever I is raised out of a recess, 19, and through its medium and the connection of the yoke with the spindle the latter may be turned without resistance from the clutch or spring, and when so turned the lever is allowed to fall into a recess, 19. \Vhen the switch is moved by a wheel ot' a passing train, the spindle is turned from the crank 1), thereby turning also the table B, and, through the sleeve B thereof, the upper part, on, of the clutch, and causing the latter to rise against the spring G, compressing it, which, eral recess in the table, substantially as dewhen the teeth of the upper part of the clutch have cleared the ends of those of the lower part, forces by its resilience the former into mesh with the latter.

\Vhat I claim as new, and desire to secure i a clutch, C, having a lower part, 91, provided by Letters Patent, is--- 1. In a switch-stand, the combination of a standard, A, supporting thelower stationary part, 02, of a clutch, t, a recessed annular table, I having a sleeve, ll, extending into the standard, the upper part, on, of the clutch extending into the lower end of the sleeve B and longitudinally but not axially movable therein, a spindle, 1), extending through the standard and clutch, a crank, l), at the end of the spindle, a spring, G, surrounding the spindle in the sleeve l3 and pressing on the clutch, a yoke, h, secured to the spindle and confining the spring at its upper end, and an operating-lever, I, substantially as described.

2. In a switch-stand, the combination of a standard, A, supporting a rectangular socket,

socket q, a recessed annular table, B, having 1 a sleeve, B, extending into the standard and j rectangular on its interior near the lower end,

the upper part, m, of the clutch having a.

rectangular shank, m, fitting into the lower end of the sleeve 13 and longitudinally movable therein, a spindle, D, extending through the standard and clutch, a crank, D, at the lower end of the spindle, a yoke, F, secured to the spindle, a spring, G, confined in the sleeve 13' between the clutch and yoke, and an operating-lever, I, substantially as described.

In a switch-stand having an annular peripherallyrecessed revoluble table normally interlocked with the spindle and a clutch having a stationary part, and a rotary part actuated against the resistance of a confined spring, G, by turning the interlocked spindle, a yoke, F, secured to the spindle and provided with a flange, Z, and extending below the flange into the opening in the table, and a lover, I, pivotally connected with the yoke and normally extending into a periphscribed.

i. A switch-stand comprising, in combination, a standard, A, having in its base aweb, r, rigidly supporting a rectangular socket, q,

with a rectangular shank, n, fitting into, the socket q, a recessed annular table, B, having a sleeve, B, extending into the standard and rectangular on its interior near the lower end, the upper part, in, of the clutch having arectangular shank, Til, fitting into the lower end of the sleeve B and longitudinally movable therein, a spindle, D, extending through the standard and clutch and having a crank, D, at its lower end, a yoke, I secured to the spindle and provided with a flange, Z, and extending below the flange into the opening in the table, a spring, i, surrounding the spindle in the sleeve B, a sleeve, II, in the sleeve B between the upper end of the spring and the yoke, and an operating-lever, I, substantially as (l(S3iil)d.

AXEL A. STROM,

In presence of- J. W. DYRENFORTH, M. J. BoWERs.
